I'm getting the following SQL error:
You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near
`classxii`.`email`='rajdeep@gmail.com', `classx`.`email`='rajdeep@gmail.com'
at line 5
My PHP code looks like:
$sql = "UPDATE `graduation`, `classxii`, `classx` SET `university`='$university', `college`='$college', `course`='$course', `branch`='$branch', `year`='$year',
`school1`='$school1', `board1`='$board1', `percentage1`='$percentage1', `year1`='$year1',
`school2`='$school2', `board2`='$board2', `percentage2`='$percentage2', `year2`='$year2'
WHERE `graduation`.`email`='$email', `classxii`.`email`='$email', `classx`.`email`='$email'";
$res = mysql_query($sql) or die(mysql_error());
What could be the issue here?
